This is seriously doing my head in!! I just don't get it.
I disabled the macbook forwarded ports as you suggested, and ran the open port check tool again; ports 1194 and 22 are still closed.
I also took the time to contact my ISP - they say its my router. What have I done wrong? I am starting to think that maybe the ports need to be opened through my ubuntu server, but again, if they weren't, I wouldn't be able to connect through the port on the LAN.
